So, I am not going to nerf the medic for now but I find a solution for give more a work to medic person, I just removed regeneration poison projectile that mean if you hit by a poison or gas so your health will take damage by 1 as per second. (Before poison headcrab hit you 15 dmg but health recovery by 11 so now it's 15 damage with 7 damage toxic. Zombie Gas Spawn, Pukepus, Poison Zombie, Ghoul and Sweep Legion and such as more will have this.)
